PTAC Unit Cleaning = an investment that adds to your bottom line

PTAC Cleaning: The Problem

PTAC units provide a cost effective way to condition or heat air in a building.
By installing PTAC units, building owners avoid spending money upfitting
an extensive central HVAC system and spending money on complex maintenance
and repair issues. They are also a more reliable form of heating and cooling.
Unlike a chilled water system that can shut down if one component fails,
PTAC units operate as self-contained units. So, if one fails, only the
room it is servicing will be affected.

However, because PTAC units are not tied into a larger centralized system,
each unit operates independently and is largely controlled by the guest
or occupant in the room. The thermostats are rarely placed on any sort
of schedule, so the units operate for much longer than conventional HVAC
systems, which are typically centrally controlled by an HVAC or maintenance
staff to be on when people are in the building, and off when people aren't
in the building. Obviously, by optimizing the schedule of an HVAC system, one can
reduce unnecessary spends on energy, etc. Consequently, PTAC units operate for much longer than they actually need to.

The longer a PTAC unit runs, the more air moves over the evaporator and
condenser coils, the more contaminants such as dirt, dust, mold spores,
moisture and pollen collect inside the unit. As these contaminants build
up inside a PTAC unit, they create odors and indoor air quality issues
and inhibit the heat exchange process. Drain pans are ideal places for
bacteria and mold to grow. Since PTAC units operate off 100% outside air,
they introduce a number of contaminants and indoor air pollutants into
the environment. Ultimately,
the effects can be very costly, such as:

Increased energy usage

Increased maintenance and repair costs

Guest/occupant dissatisfaction and loss of business

In order to
prevent these costly effects, PTAC cleaning is imperative. PTAC units need to be cleaned, disinfected
and deodorized on a regular basis. While the solution sounds simple, it's
very hard for maintenance staff to perform PTAC cleaning cost effectively.
Following conventional cleaning methods that involves PTAC cleaning to
be conducted outside, it can take the average two-person maintenance team
upwards of two hours to perform PTAC cleaning on one unit. That's
four man hours to clean one PTAC unit. Very few facilities can afford
to invest that amount of time on PTAC cleaning. This is why we see the
issues that we do.

PTAC Cleaning: Verified Savings

Each AdvantaClean PTAC cleaning project is accompanied by an Energy Study
that documents and verifies the amount of energy saved from PTAC cleaning.
Following the AdvantaClean PTAC cleaning process, you can expect to see
$50 - $100 in energy savings per PTAC unit. Below is sample data from a recent PTAC cleaning project AdvantaClean
completed at a hotel that is part of widely recognized, worldwide brand.
